Category: High Flow Filters
Series: 700
Model format: `700-[MEDIA]-[MICRON]-[SIZE]-[CORE/CAPS]-[SEAL]`
Example: `700-PO-1-40-PO-BN`

## Overview
Pleated high-retention cartridges designed for reliable absolute filtration with low initial pressure drop and extended on-stream life

## How It Works
Fluid flows outside-to-inside through pleated media, where contaminants are retained on and within the pleat pack while end seals prevent bypass

## Applications
- RO pretreatment/SDI reduction
- Desal intake/media-filter polishing
- Plant/process water particulate control
- Coolant/cutting-fluid fines removal
- Chemical batch/transfer prefilter
- Produced-water/brine solids removal
- Paints/coatings/inks guard filtration
- Electronics rinse-water prefilter
- Boiler feed/condensate fines control
- Marine ballast/potable water particulate
- Data centers: TCS CDU filtration, FWS cooling tower, chilled water filtration
